Casing Soils

Harte Peat Mushroom Casing Soil is made up of a blend of wet and dry Black Peat, wet or dry Brown Sphagnum peat and either Limestone Flour or Spent Sugar Beet Lime (SSBL), or a blend of both, to adjust pH above 7.0

Harte Peat own and control their own material resource to minimise the possibility of disease or tramp materials from getting into the mix. Peat to be used in the mix is only extracted as it is required to meet customer needs.

Following extraction, the raw peat is then transported to our production facility in Clones. The peat is then mixed to order as different customers have different requirements. The peat is mixed with Spent Sugar Beet Lime which has been weathered and stored for more than 2 years and also heat treated.

Each batch of casing soil is tested in an independent and approved laboratory for Salmonella, E-Coli and Listeria sp. before it is dispatched for use.
